there have been a few groups/people working on an oil based solution to this. i followed feelyx on pelican (
Who has done an IMS change (New Oil Fed Design Idea) - Pelican Parts Technical BBS )
who knows who started when, but i heard of feelyx's before jake's (though i'm sure jake was keeping his under wraps, so i don't mean to imply anything).
it's interesting to see, that's for sure.
